1n = 8 pigs/treatment.

2Sham = unchallenged; E. coli = E. coli challenged; CON = control diet; SMA = 0.3% smectite A; SMB = 0.3% smectite B; ZEO = 0.3% zeolite.

3E. coli = E. coli challenge effect; Diet = diet effect; E x D = interaction between E. coli and diet effects.

4Contrast between CON and all clay treatments within challenge treatments.

5Diarrhea score = 1, normal feces, 2, moist feces, 3, mild diarrhea, 4, severe diarrhea, 5, watery diarrhea.

6Pig d = number of pigs x the number of d of diarrhea scoring.

7Diarrhea d = number of pig days with diarrhea score ≥ 3. Statistical analysis was conducted by chi-square test.

8Frequency (frequency of diarrhea during the entire experimental period) = diarrhea days*100/pig days.
